The TROPO premium CoCoRaHS gauge is one of two approved CoCoRaHS gauges. Click here to see a comparison of the two!!
This is the WeatherYourWay preferred CoCoRaHS gauge. We believe you will agree, despite the slightly higher price, it is overall a better value considering the additional items included with the gauge and the quality and durability of the gauge and its parts!
The TROPO Precipitation Gauge is the next generation 4-inch all-weather professional precipitation gauge that meets the accuracy and specification requirements of CoCoRaHS. The TROPO is the approved, premium CoCoRaHS gauge option.

It’s the first comprehensive refresh of the 4-inch Stratus All-weather Rain Gauge, which was first introduced way back in 1973! Based on the design of NOAA’s National Weather Service official standard 8” rain gauge, the TROPO Precipitation Gauge uses the same dual cylinder design to measure precipitation with a resolution of 0.01” (.25 mm).
The inner cylinder holds 1 inch (25 mm) of precipitation, while the extra-large outer cylinder holds another 12.50 inches (317.5 mm) of precipitation making the maximum capacity approximately 13.5” (343 mm). The inner cylinder and funnel top cap are removable to allow catchment of snowfall or other frozen precipitation, which can then be melted down or weighed to determine a liquid equivalent.
The gauge is made of a UV stabilized Polycarbonate; the same weather resistant material as greenhouses.
This is the most advanced, accurate and easy-to-use manual precipitation gauge available.
